+# Balatro (2024, game) card-corner classifier
+
+This model classifies cropped Balatro card corners into rank and suit labels.
+It is a small shared-backbone CNN, not an Ultralytics YOLO classifier.
+
+## ONNX Interface
+
+The exported ONNX model is available at:
+
+```text
+onnx/model.onnx
+```
+
+Input:
+
+```text
+images: float32[batch, 3, 64, 64]
+```
+
+Outputs:
+
+```text
+rank_logits: float32[batch, 13]
+suit_logits: float32[batch, 4]
+```
+
+Rank label order:
+
+```text
+A, 2, 3, 4, 5, 6, 7, 8, 9, 10, J, Q, K
+```
+
+Suit label order:
+
+```text
+spades, hearts, clubs, diamonds
+```
+
+## Training Run
+
+The recovered local training run is stored at:
+
+```text
+runs/classify/card-corner-cnn/mps-aug-weighted-seed2-latest
+```
+
+The run includes `args.json`, `metrics.json`, PyTorch checkpoints, and a copy
+of the exported ONNX model under `onnx/model.onnx`.
+
+Best validation metrics from the recovered run:
+
+```text
+rank_accuracy: 0.8387096774193549
+suit_accuracy: 1.0
+exact_accuracy: 0.8387096774193549
+```
+
+## Export
+
+Use the export utility to regenerate the ONNX artifact from a checkpoint:
+
+```bash
+pixi run python cli/export-card-corner-classifier-onnx.py \
+  --checkpoint runs/classify/card-corner-cnn/mps-aug-weighted-seed2-latest/card-corner-classifier-best.pt \
+  --output models/games-balatro-2024-card-corner-classifier/onnx/model.onnx
+```
+
+## Publish
+
+After authenticating with Hugging Face, upload this model directory as the model
+repository root:
+
+```bash
+pixi run python - <<'PY'
+from huggingface_hub import HfApi
+
+repo_id = 'proj-airi/games-balatro-2024-card-corner-classifier'
+folder = 'models/games-balatro-2024-card-corner-classifier'
+
+api = HfApi()
+api.create_repo(repo_id=repo_id, repo_type='model', exist_ok=True)
+api.upload_folder(
+    repo_id=repo_id,
+    repo_type='model',
+    folder_path=folder,
+    commit_message='Add Balatro card-corner CNN ONNX model',
+)
